Any container with liquid, for example, of bank or a bottle with water, has some volume which is measured in liters. However there are cases when volume in cubic meters is known. In that case it is necessary to be able to transfer meters to liters.
Instruction
1. There are several ways of calculation of volume in liters. If you face liquid which is packed in a bottle, then there always this volume is specified in liters. However is a container whom volume is specified in cubic meters. From elementary school it is known that in 1 м^3 = 1000 l. Respectively, if you need to find the volume of any capacity in liters, you have to increase a preset value in cubic meters by 1/1000: (l) = b(м^3) * 0.001. Thus, you will be able to calculate volume in liters at the set volume measured in м^3. It is the simple transfer from one unit of measure of SI to another. However if volume is still unknown to you, it will be necessary to find at first it in meters, and then already to transfer to liters.
2. Let's say only the mass of the liquid which is in a container is known to you. By means of a simple formula which is known from a school course of physics it is possible to find volume. The formula looks so: p = m/V where m is the mass of liquid, p is liquid density. You can find liquid density, proceeding from tabular data. In all textbooks by physics density of liquids, including waters, oils, kerosene, mercury, etc. are given. Respectively, volume is equal: V = m/p (м^3). Further, also according to the scheme, V (l) = V (м^3) * 0.001.
3. If neither the volume, nor mass of a container are known to you, but it is an accurate stereometric figure, for example, a cylinder, volume can be found in two stages: in the beginning it is necessary to take experimental measurements, and then - algebraic calculations. For this purpose you need to measure the radius of the basis of a cylindrical container and its height. The volume of such container will be equal: V = πR^2 * to H where R is the radius of the basis of a container, height (m ^3) is H. Similarly, V (l) = V (м^3) * 0.001.
